Description

The NCP5500DADJR2G is a 500mA LDO voltage regulator in 8 pin SOIC package. An internal PNP pass transistor permits low dropout voltage and operation at full load current at the minimum input voltage. This regulator is ideal for applications that require a broad input voltage range and low dropout performance up to 500mA load using low cost ceramic capacitors. Integral protection features include short circuit current and thermal shutdown. It is used in post SMPS regulation, point of use regulation.
Maximum input voltage of 16V
Output voltage range from 1.25V to 5V, 230mV dropout voltage (Vdo)
Operating temperature range from -40°C to 85°C
2.9% output voltage accuracy
Reverse bias protection
Maximum line regulation of 1% at Iout = 50mA, maximum load regulation of 1% at 1mA < Iout < 500mA
Maximum current limit of 900mA at Vout = 90% of Vout(nom)
Ripple rejection ratio of 75dB at 120Hz
